CAUTION
ŘWhen operating the product always consider patient safety.
ŘUsers are responsible for the operational control, maintenance and continual inspection of this product.
ŘPrior to clinical use, inspect the handpiece. Check for vibration, noise and overheating. If any abnormalities are found, stop using the
handpiece immediately and contact your Authorized NSK Dealer. (Refer to "6. Checking the Handpiece Before Each Use")
ŘDo not disassemble or alter the handpiece except as recommended by NSK in this Operation Manual.
ŘDo not allow any impact on to the product. Do not drop the product.
ŘOperators and all others in the area must wear eye protection and a mask when operating this handpiece.

- Bent, deformed, worn, rusted, broken, deficient bur.
- Bur which is cracked on the edge or axis.
- Non-ISO(EN ISO) standard, or tampered bur.
ŘDo not use burs other than specified in "9. Specifications" as such burs may be accidentally released or break during rotation.
ŘAlways keep the bur shank clean. Debris in the chuck could cause poor bur concentricity or low chuck retention force.
ŘAlways insert the bur all the way into the chuck. If insertion is insufficient, premature failure of the handpiece head bearings, or accidental release of the bur, may occur.

CAUTION
ŘDo not exceed Max. Bur Length shown in "9. Specifications".
ŘAlways follow the instructions provided by the bur manufacturer.
ŘDo not exceed the bur speed recommended by the bur manufacturer.
ŘShould the handpiece function abnormally during use, stop using the handpiece immediately and contact your Authorized NSK Dealer.
ŘDo not use the following fluids to wipe, immerse or clean the product; strong/super acid water, strong acid/alkaline chemicals, chlorine-
containing solutions, solvents such as benzine or thinner.
ŘThe handpiece is delivered in a non-sterile condition and must be autoclaved prior to use.
ŘPerform regular function and maintenance checks. (Refer to "8. Periodical Maintenance Checks")
ŘIf the handpiece has not been used for a long period, rotate the handpiece and check for noise, vibration and overheating before use.
ŘTo avoid clinical downtime it is recommended that a spare be kept on hand in case of a breakdown during treatment.
ŘThe operation of the handpiece is permitted only on dental units which correspond to the standards IEC 60601-1 (EN 60601-1) and IEC 60601-1-2 (EN 60601-1-2).
ŘU.S. Federal law restricts this device to sale by or on the order of a licensed physician.
Z84L / Z85L / Z85
ŘUse a short shank FG bur for the product because the handpiece has the miniature head. Using a long bur with this handpiece may lead to
premature abrasion of the bearings. In addition, sudden release, bend or breakage of the bur may occur.
Z95L / Z95
ŘDo not use a surgical bur with its maximum length of 25mm or longer. Using such bur with this handpiece may lead to premature abrasion of
the bearings. In addition, sudden release, bend or breakage of the bur may occur.

CAUTION
ŘIf you wish to purge excessive oil from inside the handpiece, rotate the handpiece for approx 15 seconds without a bur. During the rotation, do
not depress the chuck release button, especially when using absorbent cloth to prevent oil from scattering. Depressing the push button during
rotation may damage the chuck mechanism.
Fig. 8 Fig. 9
NOTICE
ŘNSK recommends the use of "Spray Mist Absorber" (Y900084) to prevent oil mist expelling out of the handpiece head.

14
CAUTION
ŘIf the chuck is not regularly cleaned the chuck grip may be weakened and the bur may be accidentally released during use.
Chuck cleaning (Z84L / Z85L / Z85 / Z95L / Z95)
Clean the Push Button chuck once a week.
1) Mount the Tip Nozzle onto the spray can port.
2) Lubricate the chuck directly where the bur is inserted (Fig. 10).
3) Lubricate handpiece by using NSK PANA SPRAY Plus / PANA SPRAY (Fig. 7) or NSK automatic handpiece
